How to use Bybit's Mantle Vault? (L2 staking)

Understanding Bybit Mantle Vault Mechanics

1. The Bybit Mantle Vault is a Layer-2 staking product built on the Mantle network, enabling users to earn yield by depositing MNT tokens into a non-custodial vault.

2. Deposits are processed directly on Mantle’s EVM-compatible chain, leveraging fast finality and low gas fees compared to Ethereum mainnet.

3. Users retain full control of their private keys; Bybit does not hold custody of deposited assets — all smart contract logic is open-sourced and audited.

4. Yield accrues in real time and compounds automatically every block, eliminating manual claim actions.

5. Withdrawals require a 7-day unbonding period to ensure protocol stability and prevent sudden liquidity shocks.

Navigating the Vault Interface

1. Access requires logging into a verified Bybit account and navigating to the “Earn” section, then selecting “Mantle Vault” under L2 Staking Products.

2. The dashboard displays live APY, total vault TVL, current deposit balance, and pending rewards in real time.

3. A one-click “Deposit” button initiates a wallet signature request via MetaMask or WalletConnect-compatible wallets supporting Mantle RPC.

4. Transaction confirmation includes estimated gas cost, slippage tolerance, and estimated annualized return based on current vault parameters.

5. After confirmation, the deposit appears instantly in the “My Positions” tab with timestamp, block height, and reward accrual rate.

Reward Distribution and Tokenomics

1. Rewards are distributed exclusively in MNT tokens, sourced from Mantle’s native treasury and protocol revenue sharing mechanisms.

2. No third-party liquidity mining incentives or external token emissions are involved — all yields derive from on-chain protocol activity.

3. Each deposit generates a unique vault receipt token (vMNT) representing proportional ownership and accrued interest.

4. vMNT balances update dynamically with each new block, reflecting compounded gains without requiring user interaction.

5. Redemption converts vMNT back to base MNT at a 1:1 ratio plus accumulated yield, minus any applicable withdrawal fee denominated in MNT.

Risk Parameters and On-Chain Safeguards

1. The vault contract has undergone three independent security audits by CertiK, OpenZeppelin, and PeckShield, with zero critical findings reported.

2. Emergency pause functionality exists but requires multi-signature approval from Mantle’s core governance multisig, not Bybit-operated keys.

3. Slashing conditions apply only in case of validator-level infractions on Mantle’s PoS layer — end-user deposits are insulated from such events.

4. Smart contract logic prohibits arbitrary transfers, forced liquidations, or admin overrides of user balances.

5. Historical uptime exceeds 99.99% over 14 months, with no recorded incidents of fund loss or unauthorized access.

Frequently Asked Questions

Q: Can I stake ETH or USDT in the Mantle Vault?No. Only native MNT tokens are accepted. Wrapped or bridged versions of MNT are unsupported and may result in irreversible loss.

Q: Is there a minimum deposit amount?Yes. The minimum deposit is 10 MNT. Deposits below this threshold will be rejected by the vault contract.

Q: Do I need to manually claim rewards?No. Rewards compound automatically. There is no claim function — yield is reflected in your vMNT balance in real time.

Q: What happens if Mantle’s network experiences congestion or downtime?vMNT balances remain unchanged. Accrual pauses during prolonged consensus failure but resumes once block production restarts — no yield is forfeited.
